Winter Watering

Dry air, low precipitation, little soil moisture, and fluctuating temperatures are characteristics of fall and winter in many areas of Colorado. Often there is little or no snow cover to provide soil moisture from October through March. Trees, shrubs, perennials and lawns under these conditions may be damaged if they do not receive supplemental water.

The result of long, dry periods during fall and winter is injury or death to parts of plant root systems. Affected plants may appear perfectly normal and resume growth in the spring using stored food energy. Plants may be weakened and all or parts may die in late spring or summer when temperatures rise. Weakened plants also may be subject to insect and disease problems.

Quick Facts

• Water trees, shrubs, lawns, and perennials during prolonged dry fall and winter periods to prevent root damage that affects the health of the entire plant.

• Water only when air and soil temperatures are above 40 degrees F with no snow cover.

• Established large trees have a root spread equal to or greater than the height of the tree. Apply water to the most critical part of the root zone within the dripline.

Recycling Broken/Unwanted Holiday Lights

Don’t throw broken and burnt-out holiday light strings in your trash this season! Recyclers can separate and extract the bulbs for glass, wires for copper, and PVC for insulation materials! However, your curbside recycling company is not able to carry out this service.

Instead, take holiday lights, along with other hard-to-recycle items like batteries, electronics, bubble wrap and more, to hard-to-recycle centers, like SustainAbility, around the Denver area. And, for a limited time, SustainAbility Arvada is giving away a new set of LED string lights for free when you bring in an old set.

Can’t make it to SustainAbility for holiday string light drop-off? Visit one of these other local recycling facilities instead:

*Be sure to give them a call before you go as holiday hours may vary.

Statewide Plastic Bag Ban

Beginning Jan. 1, 2024, the Plastic Pollution Reduction Act will ban plastic bags statewide. Stores may only give out recycled paper bags for a fee. Restaurants and food prep businesses will no longer be allowed to use polystyrene (Styrofoam™) to serve food or beverages.

Avoid fees and help reduce waste by bringing your reusable bags to your favorite Broomfield stores and restaurants.

Update on City-Contracted Residential Waste Services  (Universal Waste Collection)


At the October 10, 2023 Council meeting, Broomfield City Council passed Resolution 2023-123 directing staff to issue a Request for Proposals (RFP) for City-Contracted Residential Waste Services (formerly “Universal Waste Collection”). The resolution moves Broomfield into the next phase of pursuing city-contracted services but does not enter Broomfield into a contract. Interested haulers will submit proposals to service single family homes and some small apartments (7 units or less).

The city contract would include volume-based pricing (the smaller the trash cart, the lower the rate) and embedded costs for the recycling cart (the customer pays for trash and receives a recycle cart at no additional cost). Residents have the opportunity to opt-out of the city contract subject to an opt-out fee. The RFP will explore different service options for organics (compost) collection. It will also explore any cost differences for including HOAs compared to excluding HOAs. This program alone is expected to increase Broomfield’s waste diversion by 2 to 8%.

Staff will return to Council by the second quarter of 2024 for contract review and approval, and with the related residential recycling and composting ordinance Council requested at the April 18, 2023 study session. Detailed information about costs and services will be available at that time. Services would begin in the first quarter of 2025. For more information on this program, please visit the Broomfield Voice Website.
